The operating condition of automobile requires that its motor and transmission system have the four-quadrant control function such as rotating and electric braking, but existing
Some electric braking methods can only reclaim small part energy with device in high speed, and in low speed, energy recovery rate is almost
Zero；Finally, the recycling process efficiency of braking energy feedback is not high, because the kinetic energy for reclaiming is converted into electric energy by generator,
Chemical energy is then converted to, and electric energy, kinetic energy are converted into by chemical energy when recycling, the conversion process of this energy twice can occur
Considerable loss, therefore cause the energy-saving effect of vehicle not obvious enough.

Divide to be generated electricity by first motor/generator 3 and enter battery, another part is converted into the dynamic of the flywheel 51
Energy.Because vehicle inertia is larger, the flywheel 51 and the rotor inertia of the first motor/generator 3 are smaller, first electricity
Motivation/generator 3 slows down compared with vehicle deceleration soon, when the rotating speed of the first motor/generator 3 is reduced to zero, at this moment, speed
Still it is higher.If also needing to vehicle deceleration, at this moment the first motor/generator 3 still applies negative torque, and described first is electronic
Machine/generator 3 enters opposite direction acceleration mode, i.e., into motoring condition.At this moment the kinetic energy of vehicle is completely converted into the flywheel
51 kinetic energy, while a part of electric energy is also converted into first motor/generator 3 kinetic energy of the flywheel 51, it is described
Flywheel 51 continues to accelerate, and untill vehicle deceleration stops, now the flywheel 51 keeps rotating speed high, the first motor/generating
Machine 3 keeps negative rotating speed.
Further when Brake energy recovery rear flywheel power running operating mode is in, the first clutch 2 disconnects, institute
State engine 1 and be not involved in vehicle driving, the second clutch 6 is combined, and the fly wheel brake 55 disconnects；Described first is electronic
